Having some issues with myalbum 3.08 Beta 1 from mamba7x's repository on github

We are running our test site on a local WAMP server on a PC running Windows 10, Xoops 2.5.8.1 and PHP 7.0

The first issue is that the site gives a fatal error when accessing the myalbum module from the main menu in the front end.

Fatal error: Call to undefined function extractSummary() in C:\wamp64\www\SJG2581A\modules\myalbum\class\preview.php on line 134

The myalbum module appears to be functioning well when accessing it through the control panel in the backend.

Just out of curosity we commented out the offending line of code and then were able to access the myalbum module in the front end and on initial examination it is accepting uploads, displaying the photos and categories correctly and not throwing any errors.

Not being a code expert I am not sure where to begin.

The second problem is that any of the myalbum blocks that should display a thumbnail image in the front end are not showing the images due to a malformed link. The blocks are: Random Photo, Recent Photos with thumbs and Top Photos with thumbs.

http://localhost/SJG2581A/uploads/photos//4.jpg

which should be:

http://localhost/SJG2581A/uploads/myalbum/thumbs/4.jpg

Incidentally, the thumbnails show correctly in the back end as well as in the content area of the front end.

So any and all advise and suggestions would be appreciated. We would like to see if we can use myalbum on our new site as we have had myalbum on our site since it when online in 2005 and everyone is familiar with it.

And here is the system overview information from the Control Panel:

XOOPS Version XOOPS 2.5.8.1
PHP Version 7.0.0
mySQL Version 5.7.9
Server API apache2handler
OS WINNT
fsockopen On
post_max_size 8M
max_input_time 60
output_buffering 4096
max_execution_time 120

Appreciate your efforts on xoops. Our site rebuild is looking better and better and hope to make it a reality before summer.
