no complete read out of binary data from db

[Zikan82]

i have a strange problem. i'm reading out binary data (png images) from database through cold fusion. all worked fine, but now it stopped working. the exact same script is working on another server and the images are displayed correctly. but on the other server, it doesn't work anymore(from one hour to another..). database is the same. other data from the database is read out correctly. but the binary data doesn't seem to be read out or not completely. images stay blank, because only a header is created.
i managed it, to convert the binary data, which is read out, to string and display it on both servers. result is, that on the one server, its more than one and a half site, on the not working server, it's just more or less a line of information.
any ideas, what could be wrong? kind of time-out because of the length of the data?

don't know how and why, but after 5 days of searching and now writing this entry, i looked into the cold fusion administrator and saw, that the "enable binary large object retrieval(BLOB)" was disabled... it wasn't me....
so problem is solved
