Image Upload

[brown2005]

Hi,

When uploading an image can I automatically change peoples images to width='150' height='150' and how can I do this?

And is there any downfalls to doing this?

there are indeed downfalls... what if the original is not a square image?

you will need to look at the image_create_from_gif/jpeg etc etc functions.

pretty straight forward.

I have an upload class that can handle such resizing of images etc. with the bility to take non- square images for re-sizing too (this could be adapted if you were of the inclination!)

my email is available on the left there (mainly use my hotmail acc.)

Yes there is.  Unfortunately I am at work at the moment and cannot quote from memory.

Look at the php reference document and read up on the image processing functions.  You will find what you are looking for.

It can be confusing and if you want some examples I have a number of working scripts that I would be happy to share.  One I have takes an uploaded image and automatically creates a thumbnail size version which more or less sounds what you are looking for.

Get back to me if you would like to see the script.

one bonus about html <img>... if you set width, the height scales itself down, and vice versa... so if you take a picture thats 100x200 and set

[code]
<img width="50">
[/code]

the height wil scale down to 100

But that can make the image pixelate or distort - which is awful. Setting the attributes has always been a way to control the size of the image but if you want quality with it then you shoudl adopt a more robust strategy - like properly re-creating the images.
