    Is anyone familiar with the "create thumbnail" functionality of the Image Manager?

    1. I open the Image Manager
    2. Choose an image URL
    3. Upload an image
    4. Select the uploaded image and click on the "Create thumbnail" icon in the Image Manager

    In most of the cases I get a proposed with and height of 35 Pixel although "Constrain proportions" is ticked and the image has a 4 : 3 image proportion.

    I then close the Image Manager and reopen it, select the uploaded image and click the "Create thumbnail" icon... and magic: the original width and height of the uploaded image is shown (and the state of "Constrain proportions" was kept).

    I then change the width to something smaller than the uploaded image and the height is adjusted correctly. Clicking the "Create" button generates my thumbnail. But if I select now the newly generated thumbnail, the image dimensions displayed are 35 x 35 pixel :( Clicking the "Insert" button adds the new generated image to my html content and ...the dimension are suddenly correct.

    I then reopened the Image Manager to generate a thumbnail which was a little bit wider than the one generated in the first round. So I selected the uploaded image (original dimensions correctly displayed, but if I clicked the original image a second time the dimensions always change to 35 x 35 px), ticked "Overwrite if file with such name exists?", changed the width to something larger than for the first generated thumbnail, clicked "Create", selected the new thumbnail and inserted it to my html content... and what I got inserted was the small thumbnail of the first round :(

    Only after checking in the publishing page and edit it afterwards again (close the editor) I was able to select the larger thumbnail.

    I presume the Image Manager to have two problems:

    1. Image dimensions displayed in the "create thumbnail" area are not always displayed correctly. Reproduceable is the problem when choosing an image, change to create thumbnail and click the image again on the left hand side -> dimensions always change to 35 x 35 Pixel and the only way to see the correct dimensions is to close and reopen the Image Manager
    2. Once a thumbnail is generated it looks like it get's cached ? until the Rad editor is closed. When overwriting the thumbnail the new thumbnail can only be inserted after closing and reopening the Rad editor.

    Are these issues already known?

    I am using radEditor version for MOSS and calling MOSS Image Manager in the image picker button.
    MOSS Image Manager lists atmost 8 images in thumbnail view and 15 images per page in simple view while browsing.
    Is there any way to increase the nos of images per page in the image picker?

    Hi Archana,

    What I suggest you is to upgrade to the latest version of RadEditor for MOSS, which is 5.4.1. There are  impoverishment in the FileBrowser of the dialogs. Unfortunately you can not configure how many images to shoe per page.

    You can find upgrade instructions in the following help article
