If you are using Lotus NOTES, you will find something interesting. If you copy and paste an image sometimes, you will find the document really big. The solution to that is to use paste special and then either use Device Independent BitMap or BitMap instead of RichText.
You will find the document to be significantly smaller. If you paste in RichText, the document may be > 2 Mbytes but by using paste special, the same document could be just a few hundred Kbyte.
Another thing we discovered, is you paste your content directly into Quickr document, opening such document subsequently will take several minutes. We have seen cases where it takes more than 10 minutes.
The solution is paste the content to a notepad and then copy from the notepad prior to pasting it into Quickr. Again this is probably linked to RichText.
