actually slynderdale thats what im doing now, im coding that and along with a CP frontend, the only trouble is that im trying to avoid extra database queries than i have to so im trying to think of a method to allow some sort of cacheing, either by creating a temp folder where all the thumbnails would be stored and looked up for, or create a new database table to contain all the thumbnails which would be processed when you post the attachment rather than when viewing it...

I dont mean to double post, but since no one has replied yet i have to,... I actually got the requested cache in place and options added in the Admin panel under options so you wont need to edit attachments.php everytime you want to change thumbnail sizes or change cache directories, i have included updated instructions, and im planning to add upgrade instructions just incase( i doubt you'd need it tho because its all simple enough )...

Excellent hack, just what I was looking for to be honest. A lot of my users like to post photographs of themselves and gigs they've been to, only trouble is my forum has an 800 pixel width, which always gets shunted around when people post large images. This is ideal. :D

Thanks!

^_^ thanks, if your all interested im soon going to take this hack and add it support to scott's filebased attachements then officially release it, because it seems from all the forum versions i've tested it with its been rather flawless, and when it hasnt it were mainly due to permission issues on setting up the directories, lol yeah i dont follow my own instructions :-P

Any chance of getting Image Magick support for this great hack?

Sure, ill add that to my todo list

That would be great CVMagic - Im running 3 gamma now and I know it has integrated thumbnailing of attachments but GD is limited to certain filetypes. ImageMagick supports almost all image formats, plus its much easier to install for those of us with our own servers. Much appreciated I like your clean mod.

by the way as for ImageMagick intergration do you perfer just running direct exec commands or having ImageMagick Commands intergraded into php? I much Perfer the intergraded ones over exec ones because of security reasons and the fact that some servers disallow exec commands but the thing about intergraded ones for php is that you have to rebuild your server, so ill code it accourding to what you think is best in this case.

Either way would be fine I would imagine, vbulletin is commercial product that is normally run on a dedicated server anyways. I personally have written most of my thumbnailing scripts using the system commands, ya know adding both types wouldnt really be hard since the system commands are one line using convert program.

^_^ okay im done, i just added support for No Imaging for those people who wanted to add this hack and planning to move to a new server that has GD or otherwise soon, Netpbm Support which i frankly like better than both GD and ImageMagick, ImageMagick Support for those people who want it :-D, GD2 was there already but now i have function verification so you wont get those nasty errors if lets say you dont have 2.0.1 or higher installed, and i made sure that scott's attachments as files hack wont interfere, as a side note when scott released that he was still a genious since i still dont have to modify any of his code to make this hack to work which may i say i was happy about....
So overall the requirements needed now to run this hack now are none, the requirements are set to whatever functions you have set to work rather than just GD...
Oh and i also made sure that possible security holes are covered to avoid someone sneaking in a abritary command when converting ;)...
It will be posted on the 1st post as an attachment, enjoy :)
