Vic,
Try using a file hosting service to post your images, there you will get the HTML link you shall post using Disabled Rich Text Mode. I usually insert XXXXXXXXXXX as a marker so when changing modes I can see where I shall replace the marker with the HTML reference.
I use Photobucket as my file hosting service for pictures, is free and as long as you do not use it to share movies it will be free for decades, for regular files I use Mediafire while for videos I use YouTube.
About your issue I will guess there is a possibility you have linked several summary tasks and the import is not 100% equivalent. To me it is a nuisance when importing MSP files, a lot of manual adjustment is needed; two milestones per summary task must be added to replace summary task with a hammock and you must be careful as to link predecessors and successors between summary task via the milestones only instead of to the hammock.
When I was a user of SureTrack the conversion to what they called Topic Activity was automatic. This is the only thing I am missing of good old days as I frequently must import MSP files.
Best Regards,
Rafael
