Joost posted a great article on reducing http requests on WordPress sites recently and one comment caught my attention. Nabil mentioned cSprites. It’s a WordPress plugin that merges the images in your posts into one file and uses CSS to position the single merged file in place of the original images. Here’s a good post explaining how this technique works.
Unfortunately it hasn’t been updated in over a year, and the current version doesn’t work if you have PHP 5.3.2 (and probably 5.3.1) as it trips over this PHP bug. The fix is simple, get rid of call_user_func_array() and call the functions directly.
I had it installed here and it worked well enough but not perfectly. Here’s the post I made on the plugin’s support forum if anyone’s interested.
I don’t think the author will update the plugin again and in fact he’s looking for someone else to take over. Anyone?
The plugin has been running on my photoblog for the last hour ago and I haven’t noticed any problems yet. As a bonus, it also stops people right clicking and stealing saving my photos for their own use. I’ve since removed it as visitors were only seeing blank images. Oh well.
Oh yeah, there’s also the SpriteMe bookmarklet if you don’t want to go fiddling with WordPress plugins!
