Hello
Version Joomla 373 et Jsitemappro 435

The XLM sitemap and XML mobile sitemap are ok, therefore I think the data sources are OK
The precaching ajax is ok for both XLM sitemap and XML mobile sitemap

the xml image sitemap is not complete
I have on my website virtuemart shop plus a lot of pictures (2600 approximatly) embedded in html articles

the image XML sitemap :
it takes the vir[tuemart shop perfectly
it starts the html articles but stops without finishing all the articles

I have read your documentation
I think it is a problem of limit of memory

I have enabled precaching ajax
with limit for images/videos sitemap = 50
resquets limit (I have tried everything with no success) - now it is on 200 - 5 min

when I try the precaching image sitemap
the first screen data source have been retrieved is ok
the second screen virtuemart category looks ok
then a red screen appears written -error- and it stopped
the precaching is not done

Can you help me to find the reason
