External storage of images


Recommended Posts

Hi All,


It is great that the TCP membership is so willing and able to share photos of work on the forum. There are several methods for posting one's photos. The main one is to attach a photo of the recommended size around 640 x 480 pixel size and 50 kb file size.


A few contributors are finding a way to load images directly from their web site or photo storage sites. With this option, the file dimension and file size will not affect the forum's storage capacity. The drawbacks for this option are: 1. the larger images take longer to load for members with very slow modems (I am among them, at 26,400 bps on good days) to complete a single or multiple image contribution; and 2. if you change the storage site in any way that will alter the forum's connection to the off site image, the posted images will not appear in the posts, leaving great holes in the forum's image resources.


So if you choose to use off site storage for images posted in TCP, be sure that it will remain available in the exactly same way into perpetuity. Also, remember to offer a friendly size to the forum, as in follow the 640 x 480 pixel size, 50 kb file size (approximate zone, O.K. to stretch a little guidelines), so that the members are able to enjoy a reasonable image loading speed.


We TCP admin actually prefer that you would take the time to prepare the photos and attach them to TCP storage, so that the future image resources for the forum will remain whole and intact.


Thank you for your willingness to share photographis images. Your efforts to do this multiplies the strength of the information you all share here on this great forum.

I'd also just like to add my appreciation to Janel's for the efforts of everyone who does go to the trouble post images. Thanks all :D


To be just a little picky though could I gently suggest that when you do post an image you crop it so that only the actual object is shown. I have wireless broadband so my download speeds are like lightning but I can imagine what it must feel like to watch an image slowly download only to find that 70% is unnecessary background.


If you don't have a photo editing program to do this you can download Irfanview for free here.

It's a very easy program to use, will resize, crop and also perform some other basic editing for you. This is a very well known piece of freeware and has an excellent reputation.


But what ever you do, keep 'em coming boys and girls :blink:

another thing that can be adjusted in your images to reduce the file size is the image resolution. If you want to print an image then a reseolutionof 300 dpi (dots per inch) would be standard but as our monitors generally don't show that much detail you can reduce the dpi to 72 with no visible loss of quality.

a third free image editor would be gimp which is under a general public license

available for Windows or Linux, and a common substitute for Photoshop on the Linux platform, its a powerful free raster image editor


there will likely be an expiration date on most free image hosting sites

in the event an image is hosted off a website there is the hope it was captured by one of the many web caches

the leading one being the internet archive's wayback machine


for those using Firefox there is an extension called cache view which adds the option to your right click menu of checking several web caches for the dead link (an absolute must IMO)


there are also Wayback Machine search engine plugins at the Mycroft Project for the embedded search windows in both Firefox and Internet Explorer 7


in the event someone elects to host remotely when coding images in BBcode (the code this forum uses) you can create a thumbnail that enlarges when clicked with this format

(url=http://location full size)(IMG)http://location thumbnail(/IMG)(/url)

just substitute parentheses ( ) with brackets [ ]


example click to enlarge, quote to reveal example code with brackets






(image source: http://en.wikipedia.org/wiki/Image:Damascening.jpg, granted to copy or distribute under the GNU free documentation license)

it will expire eventually, and most free image hosting sites have a robot exclusion preventing capture in at least the internet archive. Google cache may have it for a short period of time.


Opening this forum to outside documentation and archival activities



seems to extend only as far as the main directory currently

and even when a website is archived, sometimes images are not


if your interested Janel the archive offers the archive-it subscription service to institutions and individuals

FAQ (its free) terms

alternately there are links to the robot exclusion files in that FAQ

(which you might already have in place :rolleyes: but figured others here have their own sites as well :rolleyes: )

Hi Chuck,


The remotely stored images, if ever anything changes with them, creates a loss for TCP. That is why we encourage the members to resize/edit photos to the guidelines and attaching them to your posts. The storage issue is not a great problem, if everyone keeps the file sizes around 50 kb or there abouts.


Thanks for the interesting information.

hmmm... guess I wasn't too clear :rolleyes: (or was still editing, the above post, snip and paste)


you can load both a smaller image on the forum for archival as well as a more detailed view of any size hosted remotely that will not burden the TCP server


though you have to edit it in manually (quote to reveal sample)


(url=http://location of full size)(attachment=XXXX:_title.jpg)(/url)

again substitute [ for (


attach as normal then edit in the supersized detail on a remote server

you get the best of both worlds :rolleyes:


you remove one of the likely reasons someone might want to host remotely, and while the supersize may eventually go away the picture attached (per recommended guidelines) will remain, clicking the photo then will just bring up a dead link
