What about making the title of a photo a link to the 'search term category' related?
Image to search the generic term 'football', you'll get this page:
http://www.dreamstime.com/search.php?srh_field=football&firstvalue=football&lastsearchvalue=football&x=31&y=9&s_ph=y&s_il=y&s_sm=all&s_rf=y&s_ed=y&s_st=new&memso=y&s_cf=1&s_catid=&s_cliid=&s_colid=&memorize_search=1&s_exc=&s_excp=&s_sp=&s_sl1=y&s_sl2=y&s_sl3=y&s_sl4=y&s_sl5=y&s_color1=FFFFFF&s_percent1=10&s_color2=FFFFFF&s_percent2=10&s_rsf=0&s_rst=7&s_clc=y&s_clm=y&s_orp=y&s_ors=y&s_orl=y&s_orw=y
The 2nd photo (order by relevancy/descending) is 4840421 American football
Now, image to have a button on the right near the photo title linking automatically to all results with new search kword 'american football' (keyword is always depending on the photo).
Result in this case would be:
http://www.dreamstime.com/search.php?srh_field=american+football&firstvalue=american+football&lastsearchvalue=football&s_ph=y&s_il=y&s_sm=all&s_rf=y&s_ed=y&s_st=new&memso=y&s_cf=1&s_catid=&s_cliid=&s_colid=&memorize_search=1&s_exc=&s_excp=&s_sp=&s_sl1=y&s_sl2=y&s_sl3=y&s_sl4=y&s_sl5=y&s_color1=FFFFFF&s_percent1=10&s_color2=FFFFFF&s_percent2=10&s_rsf=0&s_rst=7&s_clc=y&s_clm=y&s_orp=y&s_ors=y&s_orl=y&s_orw=y
This would allow users to search quickly more results on each specific interest in that moment, generating the 'keyword category' usefull just clicking near the photo title.
Thanks posted in Photo title becoming 'search category link'
