My fan art

Unfortunitly I don't know how it could be done without resizing it in MSPaint (or if you use a Mac, whatever that equivilant is). Sorry. =/

Yes, go to Start, up to Programs, over to Accessories, down to Paint. Once it's open, go to File, then Open, find the image you want to resize, double click it. Once it's open you go to Image, and Resize. Then just bring it in as much as you want.

However I use Irfanview to resize images. It's a nice program that allows you to do simple things like resizing, cropping, tints, blur/sharpen, black and white, dark/light, contrast, etc. You can't draw like you can in paint or photoshop, but it's a quick alternative to loading up photoshop or dealing with paint. And I just don't really like messing with paint. With Irfanview you know how big your image is. With paint I'm finding that it's done in percentages.

Just a note, but it's something I do with scanned things or pictures from my camera, keep the original scans the size they are, and when you save the smaller versions save them under a different name. This way if you ever print them out you use the originals and get better quality.

Photoshop is available, in part, for free at http://photoshop.com/. What program do you use to scan? That's initially all you need to get your fan art digitized and web-ready.
