[TIP] Basic thumbnail solution, using .thumb_ instead of TV image

I guess that you are using "Text" input type for your image TV and, subsequently, you are manually filling in value for your image, for example, as: "someimage.jpg", but please consider that the snippet needs to know both correct path of the image and image’s name itself -- otherwise, the image does not exist from the point of snippet’s view. All snippets in MODx are parsed by main index.php file located in root folder and from this perspective images are seen by all snippets. So, correct value for image TV -- when manually inserted -- should be "assets/images/someimage.jpg" (provided that you are keeping them in standard folder). Or, alternatively, simply use "Image" input type for your TV thus allowing MODx to take care of providing TV’s value with correct path for your image.

Hi Alik,

Thanks for you post, but I’m using the image widget not a text path. the image widget automates the thumbnail creation so I don’t think it is this, unless of course I’m missing something?

If you have the widget type set to image, that may be your problem. With just the TV set as Image and no widget, the TV value will only be the path (and the thumbnails are created upon upload), which is what this snippet looks for. Adding the Image type widget param adds <img src=""> around the TV value automatically and probably causes the snippet to fail.

That’s correct. Extra code returned by the widget causes that the snippet is unable to find image (let alone its thumbnail).

Thank you guys,

Indeed this was causing the problem it is now working fine. Thank you all for your time.

Right, now to look for more things i can get my self in a pickle over

The thumbs that are created are 96x96 pixels. Is it possible to get them bigger somehow?

Thank you Breezer. I was trying out this snippet you’re right, it’s not working with Image set as widget.

I’d like to ask: Can I still use this snippet even with the Image Widget turned on? Thanks in advance guys.

Hi all,
Has anyone got a quick’n’dirty solution for accessing the thumbnails generated by fckeditor/the file manager?

I didn’t even know that the file manager could generate thumbnails! How do you get it to do this?

Every image that I have uploaded (to the assets/images folder) using the file manager, only shows with a built-in MODx "camera" icon/thumbnail when using the editor "Insert image" requester.

(I’m using MODx 1.0.2)

Mentioned thumbnails are generated by MODx when you access file folder via TV of input type "image".
