I like how easy it was to upload my own photos, as well! It's very user friendly for beginners who are looking into this type thing but don't know where/how too start out with their photography business or portfolio building process - textures has helped me in creating an online presence through social media (Facebook).
There isn’t much you can do about your photo quality when uploading them; however they offer tips if needed so there shouldn' t be any problems at least not from what i've seen thus far!! If anyone wants help setting up portfolios then use texturez. They have really made things easier by allowing people without expensive equipment accessable ways such as taking advantage off other peoples hard work done already which makes sense because we're using others images anyway right?
