is there anyway to prevent sitespinner from changing the names of photos, like if i have duhaas.jpg, it renames it when i publish to like objxndhaksdfhsa.jpg for example

You can assign a name of your choice to your photo using the Object drop-down menu.

SiteSPinner renames image files to the objXX... file name whenever you alter the image inside SS (such as resizing it) or forcing it to re-render.

If you find you are resizing a lot of your images, you may want to resize them outside of SS using an external image processing program then import them into your project. Two free programs are IrfanView (very good for batch changes) and Paint.Net.
