I have just recently been using wordpress and wppa, so excuse me if my question is stupid, i have searched all forums but i havent found what I am looking for.
When I upload a picture into an album, the "weight" (kb) is 3 times higher after my upload. Ex: lets say the picture I upload is 40kb, once it is on the site, it has become 130kb. I cannot find any notion of it in the settings and I dont understand why/how this happens.
Also, is there a way to keep the filename as is? instead of changing it to a number? SEO helps when the image file describes the image.
