I am newbie of Drupal. Now I am constructing my site with Drupal7 under following condition.

Drupal 7
Apache version : 1.3.39(unix)
PHP version :5.2.14
Sqlite

When I upload jpeg image with image field, Jpeg thumbnail is not displayed.
But GIF and PNG thumbnail is displayed without any problem.
I found that when I upload GIF or PNG, thumbnail data is generated in

sites/default/files/styles/thumbnail/public.

But in the case of jpeg, thumbnail data is not generated.
Because of this problem I can not show jpeg thumbnail in my site at all.
Could you kindly advice me some solution. Thank you in advance.

What is the extension of the file - jpg or JPG? Rename it to JPG (with capital letters) and try again. Is there any difference?

I am having the same issue

Drupal 7.2
Apache version : 2 (CentOS Linux 5.6)
PHP version :5.3
MYsql

PNG and GIF work fine. I tired all forms of jpg, jpeg, JPG and JPEG and none work. Any solution?

In my case, the issue happened because GD library for jpeg support was not installed in my php. After installing it, jpeg was displayed without any problem.
