It is a completely and utterly fantastic plugin for WordPress. It makes it extremely easy to upload pictures, make thumbnails, downscale and watermark. All from the standard WordPress web GUI in a very user friendly system.
It took some time before I could find the controls in the WEB-gui. I had to apply a fix for the way DreamHost run PHP. What you do is:
For Exhibit, you might find this useful (a user contribution to Dreamhost’s really quite useful KnowledgeBase)
In exhibit10.php, there is a block of code near the very beginning (line 46) that says:
Remove that whole block and replace it with:
$_SERVER['SCRIPT_NAME'] = $_SERVER['SCRIPT_URL'];
Before I found that, I couldn’t get Exhibit to appear in the admin interface
 Not me – found it after much head-scratching and googling
 Understatement – it’s an excellent resource for DH users
In addition to this you have to do a fix for WordPress 1.5:
In the file “exhibit10.php”, around line 130, you should find this line:
$this->tableexhibit = $table_prefix . $this->exhibit_db_table;
I replaced this line with this:
$this->tableexhibit = “wp_exhibit”;
I found these fixes here:
The thumbnails at the top of this post are inserted using the Exhibit plugin.
