• I have upgraded to 2.0 and when I upload a file with wordpress, when I click on the photo in the image browser n the post editor window, I get “No Thumbnail” crossed out. How can I diagnose this? Has anyone else had this problem or am I missing something?

    bump!

    Are the dimensions of the original picture greater than 128 (width) or 96 (height)? If not, no thumbnail is created and therefore the menu item is crossed out.

    I have exactely the same problem and I desparately don’t know how to fix that…

    1. What type of image did you upload? gif, jgep, png?

    2. Check if the thumbnail was created after the upload in your “uploads/2006/01” folder. E.g., if you uploaded a picture with the filename “tree.jpg” then the thumbnail must be in the same folder named “tree.thumbnail.jpg”.

    Thanks for your response! To answer your questions:

    1. The pictures have been shot with a 3 megapixel camera, are about 750K in size and I believe the dimensions are – 1536×2048

    2. The files I have been uploading are jpegs from my digital camera.

    3. Examining the upload directory, all I can find is the file I uploaded.

    So I am really puzzled. I can go ahead and insert an image into my posts using this facility, its just there are no thumbnails being generated. All the UI is showing me is the words “No Thumbnail” crossed out, so WordPress is not happy with something.

    As near as I can tell, this has been my only major problem with the upgrade from 1.5.x

    Any advice on how to diagnose this problem with be greatly appreciated. Does WP generate logs somewhere that I can look at?

    Your picture has to many pixels for the function to generate a thumbnail. It’s strange but that’s what the programmers implemented.

    Don’t worry, you can do something about it.

    I figured this out right before I saw you posted! (though I didn’t know how to fix it). I by chance uploaded one of my images that had been sized down to like 600×450 and viola! it worked.

    I have tweaked the settings as suggested in the post you linked to and it’s sorted. Cool stuff and thanks again.

    Hi,

    I’m getting the exact same problem as this with all sizes of images, the inline uploader doesn’t seem to create any thumbnails for me.

    On a varied selection of sized images, I even tried a 600×450, but I always get ‘No Thumbnail’ with a strike through. When I click on it I get this message ‘There is no thumbnail associated with this photo’.

    I’ve tried both JPEGs and PNGs with no joy, and have the latest version of Image Magick on the server.

    Anyone shed any light on this ?

    thanks

    Hello –

    I too am having this same exact issue.. ?? It does not matter what image size I try to upload, I always see No Thumbnail w/ a strike thru..

    I recently upgraded to 2.02 and moved to a windows 2003 server at the same time, but I did a complete fresh reinstall of WP2.02, only restoring a backup of the DB.. so everything should be new, but could this have something to do w/ the no thumbnails?? Of course everything was fine before the upgrade/move :S any ideas at all? I’ve been all over this forum w/ no luck..

    I am desperatly needing to fix this, as it’s my girlfriends blog and she’s been buggin for thumbnails! ?? .. thx for ANY help!!

    Hami and Chillware,

    The current WP upload tool works such that it won’t create thumbnails for images above a certain size. I guess the programmers wanted to help you save your gig space.

    What you want to do is open your inline-uploading.php file.

    On line 83 or so, where you see:

    if ( $imagedata[‘width’] * $imagedata[‘height’] < 3 * 1024 * 1024 ) {

    You can change the limitation to however large you’d like.

    For example, you can change the “3 * 1024 * 1024” to something like:

    100*100*100*100*100*100

    I’m sure you get the point.

    If that doesn’t work, try installing the latest version of WP. Maybe you might’ve altered code somewhere? That will help you compare your coding.

    I just installed a new version of the latest WordPress, and it worked successfully. So it should work for you.

    Hope that helps you!

    Sorry for the bump, but this is the first result for “no thumbnail” and I thought I’d add what fixed this for me. After a fresh install of the newest version, I was having this thumbnail issue. I tried the inline-updloading hack, but that didn’t fix it for me. I poked around the code and found the thumbnail making function (wp_create_thumbnail). Before it attempts to create thumbnails, it verifies that you have the required php functions available (imagegif, imagejpeg, etc). If you don’t, it’ll fail silently. All I had to do was enable these functions in PHP by uncommenting the “extension=php_gd2.dll” line in my php.ini. I tried an image upload again and, voila, thumbnails!

    Hello, i installed simpleT and am unable to get thumbnails (i just get a link to the page). i have tried to do above instructions and nothing has worked, though i can’t completely understand them all.

    I would be grateful for any sort of simple explanation.

    I’m having the same problem as some of the users above. When I upload a picture, I get no error, but when I click on a picture (in “Browse all” or so) there is a text “No thumbnail” with a strike through. When I click on that it says “There is no thumbnail assoiciated”. The solutions posted above don’t work for me.

    Any suggestions how to fix this? Thanks in advance.

    (I’m running version 2.0.4 without any special plug-ins on Linux (Ubuntu).)

    I have the smae problem it was working fine few days ago
