The images straight off the PS3 are huge, I started cropping stuff and converting it to a jpg at first just because I didn't want to have loading issues... didn't want spoiler tags, and one thing led to another ...
I have been playing around with Photoshop Elements ..... but there are a lot of free programs that will do the trick too.
I haven't been using any really advanced techniques or features .... basic stuff like the eraser and layering... some text..... You might check out Tucows .... (they have a lot of freeware) and before I had this version of Photoshop I used some software I got there to do about the same thing. (.... that was a long time ago though so I don't know what to suggest now.)
There are a couple of reasons I started putting images off site...
-I already had a blog (for other reasons and interests) so I felt comfortable using it.
-Where I work they block sites that use the word game... too many people played solitaire ....So this site was blocked.
-I had a lot of images ... and I was having difficulty structuring it all here...
- Sometimes I like looking at my WIP and thinking about where I want to go next. I wouldn't necessarily want to post that here.
I hope this helps ... I have a few collages up on my thread right now (sorry for the plug )
