Auto Watermark?

[johnnypowpow]

Hi, I've seen in a few other scripts using both the GD library and Imagemagick that you can have the script do an auto-watermark on the full-size images upon upload.

I have the php script for a gallery called photopost that does this if anyone could look it over and see if this could be applied to 4images.

[V@no]

I'm interesting in it too. where I can get that script?

I use a Photoshop action to insert my url automaticly. You just have to load the watermark and than start the action.

the problem with that is then the thumbnail generated will have that watermark on it as well....would be tough to see the thumbnail image very well.

the script i'm talking about is a seperate php gallery app called photopost.
if anyone could look at photopost and then make a mod to 4images to make that work......email me at:

Or download the zip file i added

Thought it works, but.. it didn't.

Is it only working when uploading pictures after installation of this mod/plugin? Or should I be able to let it run on all images I've got?

Tried uploading an image, but it didn't get the watermark.

I downloaded the version from here, and didn't type it myself.

[mawenzi]

... can have the script do an auto-watermark on the full-size images upon upload.

... it is possibile ...
... there are some 4images MODs, they all together can do this ...

1. [TUT] One Image - Three sizes : http://www.4homepages.de/forum/index.php?topic=20496.0
... this MODs will save your full size image in a extra folder upon a upload ...
... and resize the image for your detail page ...
... and generate a download link to your full size image via download button ...

2. [MOD] Image Annotations (Watermark) : http://www.4homepages.de/forum/index.php?topic=13719.0
... this MOD generate a watermak to your images upon a upload ...
... there you must change the settings to generate the watermark only on the full size images ...

I think that's all for your request...

[EdwinK]

Tried this, but after been trying for some time, I still don't get it to work. I did so many changes to the files, I now don't longer know what file is doing what. Going to try to restore all files to as they were when I first downloaded them.

@ EdwinK

... it's right and I know, it's a hard piece of work and coding ...
... but the instructions are all already there ... and finaly it works in the way as I have described ...

This is what I got now:
