PHP Question (newbie) images and php

[Cashew]

Hello, I have a question about PHP I am looking to do the following I would like it whereas when you upload a image via ftp, this image

is automaticlly created into a thumbnail and put within a slice, then when you click that link (slice) from a client point-of-view it loads the full screen image in a java pop up window, Is this possible ? One other thing concerns me though since alot of browsers nowadays can block pop-ups is there a way to force a pop-up dispite the browser has it blocked ?

[Yesideez]

Forcing pop-ups is frowned upon and I doubt you'll get help with that here, certainly not from me.

 

Yes, everything is possible.

 

I prefer to have most things open in the same window.

[Cashew]

Well I will think of another way with the pop-up.  So the rest is possible how would you go about this ? I know for some of you this may or may not be simple stuff.  So this can be all done within HTML?

[Yesideez]

You'll definitely need PHP as you'll need to do some scripting or some other like ASP.

 

I've not played with making thumbnails from images but I have written a file manager where users can upload files to the server. For that I used HTML, PHP and for ease of use I had it running with a MySQL database to keep track of the files.

 

I'm sure others will be able to give you more information than this. Very sorry if its a bit vague but its late and I'm soon off to bed!

[Cashew]

Alright, hopefully someone offers some help.

[Yesideez]

What I'd do is look for some sample scripts to upload files and to resize images. Play with them and see how they work then start on writing your own or modifying the existing ones to do what you want.

 

As you go along you'll learn quite a bit and you can always come back here and ask questions if you get stuck.

 

Have fun!

And to avoid using a pop-up, but elegantly displaying the full image, Google Lightbox.  It's a free javascript app, and it's the best I've seen.

Oh alright.  Still waiting on some help with the PHP and images.  Thank You

Oh, thank you.  So I just put this in the HTML and put the image file names ? I wanted to use lightbox for the image pop up is that put in that aswell ? I didn't expect this I should try this out.  So it creates a thumbnail and put it within a slice ? Then when the slice\link is clicked the java (lightbox) pops up showing this image and this is all automatic all I do is upload the image via ftp and that's it ?
