Scaled Image Instances

[Wil]

I may be missing something obvious, but when trying to automatically scale image and image into 3 versions (small, medium & large) I'm having trouble.

The applet seems to do something extra, then upload no problem but there is only 1 version of each image and that version doesn't open.

Without the instances it works a charm. Here's the applet code anyway:

After changing the extension of the uploaded file from jpg to zip I could see the uploaded had created the instances and zipped them up - so that's working fine.

The question is then, how do I get the uploader not to zip them and just upload each instance?

It might be worth mentioning now that I need the applet to resize them no matter if the resize instance is larger than the original. It would be great if it could do it to a maximum x / y value. Say if I want the image to be no larger than 300px wide OR 300px high, so a 400x250 would be resized to 300x188 and vice versa.

Can hardly imagine what could be wrong - although actual web page is slightly modified than provided in this post, all seems to be processed correctly.

I would recommend to narrow problem - this could be problem on client (image processing, creating zip) or on server (file retrieval). Please check that temporary zip file (you can read it's path from console: C:\Users\WIL~1.LIN\AppData\Local\Temp\tmp_61646.zip) - is it OK?

Yea, it's all fine it looks like that's the file that's been uploaded but renamed as a jpg.

It is not possible to upload scaled images one by one - only in zip.
You can stretch images using <param name="uc_stretchImages" value="true"/>. Dimension specify bounding box, not target image dimension. All scaled images aspect ratio preserved. So, if you want, let's say, make all scaled images 300px wide (regardless its height), just specify really big value for height, i.e. 300x10000.

So to retrieve the scaled images I would need to extract the zip file? I can see from the php that it's detected the right content type, but somehow mapped the wrong extension, I can catch that.

Just to double check, when uploading scaled images it will only zip and upload them as one file?

I've quickly altered the PHP script you gave as an example to unzip and prefix the uploaded images as instances. It unzips and copies each entry in the zip and renames them according to their original name and instance name.

For example, uploading an image called 'my-image.jpg' with two instance names of 'small' and 'large' would produce two unzipped images in the orignal upload folder called 'my-image_small.jpg' and my-image_large.jpg'.

I thought it might come in useful so here it is:

thank you.

Great php! This was exactly what I needed. This is a good help if you want to create an album with thumbnails.
One detail: I noticed that the temp files in the unzipped directory weren't deleted.
I adjusted the lines below:

rename ($source,$target);
unlink ($target_file_path);
}
}
closedir($handle);

into:

rename ($source,$target);
unlink ($source); // deletes the temp file in the unzipped dir
}
}
unlink ($target_file_path); // deletes the .zip file
closedir($handle);
