Actually by php I want to resize the image first then that image will be uploaded.

I am a beginner, I have some knowledge of html and understand that php is better with uploading files (which I can’t do with html either), but I can’t really get anything out of the tutorials on the web. I really need someone to tell me elementary style how to get started with step by step process. I would really appreciate your knowledge.

i have created a website. I also uploaded php files in that site.How does that php files reflects in the website

Please help it is very annoying.
When I try to upload pictures or photos to websites, even by using simple uploader, a blank page appears and it has some extension like php and the upload is not successful it happens in various websites like facebook and other kind of internet website. I don`t know why it started happenning? What should I do any ideas?
