Operation Manual Index
You must create at least one category before you can upload images. The configuration options are summarised below:
Field Description Category name: Give your category an appropriate name. Keep it short, as people will select it through a drop-down box. Select groups for image manager use Select the user groups that you want to be able to access the images in this category. These groups will be able to see and select images (for use in submissions etc.) but cannot upload new images. The Webmaster group has access by default. Select groups allowed to upload images: Select the user groups you want to permit to upload new images into this category. The default is upload by the Webmaster group only. Typically upload rights are given to trusted (administrative) groups only. Bear in mind that if you allow the general public to upload images they may send in some offensive ones. Max size allowed (kb): It is useful to impose a limit on the file size uploaded images. This prevents people from posting ridiculously large images that are difficult to download. The default is 50,000 bytes (it is not KB as stated, that is an error). Max width allowed (pixels): Set a maximum width on images to preserve the integrity of your layout. Consider what would happen if someone uses a 1024 pixel wide image on your 800 pixel wide site! If you have a standard size you like to use for your site this is a good place to set it. Max height allowed (pixels): As above. Display order in image manager: You can set the order in which categories appear in the image manager drop down box here. If you want to have some flexibility in ordering the categories, assign them order numbers in (say) multiples of 10. That way you can always come back and insert a new category between them. Display this category? The default is yes. If you choose no, the category will be hidden when people access the image manager from the user side. This can be useful for hiding administrative categories from your users. Images are uploaded to: There are two options here (and you cannot change your mind afterwards). You can: store images as files in the uploads directory (default), or
store images as binary blob data in the database.
The difference is that option two actually stores the image in the database, while option one does not (it stores a reference to the image location instead).
The advantage of option two is that when you back up your database you will back up your images as well. However, images take up a lot of space, so your database file will be much bigger. If your website is hosted remotely and you have to download the backup file it will take a lot longer.
