FYI - No one from MSMW staff has responded to queries on the forum or external contact requests for the last year. I'm just another client like you lending a helping hand.
Regarding your image issue, go into the theme admin under "Image Resizing" and switch it from "TimThumb" to "Built-in WordPress". See if that fixes your problem.
NOTE: Don't use TimThumb...it is not secure.
Hope that helps.
Regarding downloading themes...
I couldn't wait forever for MSMW to get back in the game since I am a Managed WordPress Cloud supplier who needs to support clients on the defunct MSMW themes so I created a community fork of the open source MSMW themes at https://backstopthemes.com and upgraded the code to support php7 and WordPress 4.7 (I'm bringing the jquery up-to-date next). For the techies, you can participate in the community at https://gitlab.com/BackStopThemes.
NOTE: This excludes Awake and inFocus since these are proprietary ThemeForest distributed themes.
BackStop Themes instructions:
Note: Always make a backup of your current system before upgrading your theme in case you want to roll back.
Manual upgrade options are:
a) Copy the new folder contents into the old folder; OR;
b) Rename the old folder, upload the new folder; OR;
c) Delete the old folder, upload the new folder
I tend to use option b.
Remember to download a copy of the old theme folder first as a backup. If you upgrade using option b or c you will need to copy your skin folder and css file from the backup theme copy folder to the new live theme folder.
FYI - BackStop themes is a community-based support environment for the now defunct MSMW themes. Please keep in mind that support is now community based so please be patient. None of the money you spend / have spent on MySiteMyWay goes to the new community-based support environment which was established and is maintained by OnePressTech Pty Ltd.
If you choose to continue with BackStop Themes you can email firstname.lastname@example.org to be added to the BackStop Themes newsletter....welcome to the new community :-)
