I've been collecting Photoshop tutorials for a while, and these are some of the best I've seen! If you don't have Photoshop, try out the GIMP. it's a free program that's very similar to Photoshop.
Again, if you don't have Photoshop, never fear!! I highly recommend the GIMP (click it to go to the homepage). It's absolutely free, and the tools in it are almost the same as Photoshop. If you need help learning how to use the GIMP, go to this website.
Make3D is a website that allows you to make your photos into 3D models! It's really neat. Though it's not perfect (nothing is), it's still neat to play around with. The site does require you to register to make your own, but to look at what other people have made doesn't require anything. But, everything's free!
Here's an example of what someone did to their photo.
I found this and was very impressed. Pixlr is a sort of online Photoshop tool that lets you creat graphics and edit photos all online! There's no downloads required (however you can download one of their little applications to open images directly into it), and it's completely free! Pixlr "brings you advanced online image and photo editing tools, just choose your flavor, jump in and start creating!"
The website, "Unrelated Captions" is dedicated to pictures that have captions with little to no relation with the picture in question. Their slogan is appropriate: "Accidentally hilarious."
These photos are amazing! The list's description is, "Sporting events garner so much media attention these days that you can be certain that anytime something goes wrong, someone will catch it on film." This hilarious list of mishaps simply can't be missed.
