Your site probably has plenty of images, at least it should. Images really pull a site together, so long as they are relevant. For most of us, the images we use are licensed from other people - this means that you aren't the only one with them.
Image searches don't like to show duplicate images. They only show one source for one image. This means that to get your image listed, you may need to use some SEO sense:
Size distinguishes images - offer the images scaled to sizes other than the original. Not only does this show you have different images, but it means you show up under images searches for small, medium and large images. Give a few size option links below each image. Golddust tip: having your image available larger than the original makes it appear that you have the authentic source - even if the quality is reduced.
Filenames matter - DSC000324.jpg won't do you any favours - get more image hits by naming it 'lesbian_orgy.jpg' or whatever the photo is about.
Icing the cake - Use strong keyword-based anchor text to link to your fullsize version, and put text next to it to the same effect. Don't forget the ALT tag for the image, and the TITLE tag for the link.
File Formats - try to differentiate yourself by using different file formats to the original. In particular, change formats to .jpg.
Frame Busting - consider framebusting javascript to remove the frame around the image search results. Your results with this may vary. Think about obfusicating the code so that search engines don't know it's there.
