i have a photoshopd picture with layers, and when i save as a jpeg it looks nasty in myspace, myspace only accepts PNG,JPG,TIFF,BMP or GIF image file, is there any ways i can get around/save this and keep the layers and edits?

if you save a version for yourself, .psd, and a version for the web, .jpg/.png/etc, you can access your own version to make edits later. the web versions are not editable but if you want to share your layers with someone you can send them the psd.
