Blob

Defines a blob field type. The blob field has no input or display, instead it acts merely as a structural tool. Other modules can add widgets and display handlers for special case blobs.

This module is handy if you are writing something that needs to store blobs related to entities. Input widget and formatter can then be written for your case, or you can manually handle the data.

Depending on the size of the blobs you may want to use field_suppress to alleviate excessive memory usage.
