Shares in Photoshop maker Adobe Systems Inc soared to lifetime highs on Friday, a day after it announced plans to buy stock photography company Fotolia for $800 million and a quarterly jump in subscribers of Creative Cloud.

The stock rose more than 10 percent, trading at $76.70 per share as of 1733 GMT as several brokerages published raised price targets.

The company said it would integrate Fotolia, which offers royalty-free stock photos and video, with CreativeCloud to raise its average revenue per user, while Fotolia will continue as a standalone service.

Adobe is being helped by demand from corporatecustomers. Chief Financial Officer Mark Garrett told Reutersdeals with were "getting bigger and bigger".

Garrett added that Adobe, which loses about a third of itsrevenue through pirated software, is considering a number ofoptions to combat piracy including making a feature in Adobe's Photoshop available only to users who log into the cloud.

The company said it added 644,000 new Creative Cloudsubscriptions in the fourth quarter which ended on Nov. 28 but noted seasonal factors would trim growth in the current quarter.

"(It) is very typical for software companies because software purchasers have been trained to buy software atthe end of the quarter and at the end of the fiscal year. That'swhen you get the best deals," Brendan Barnicle, an analyst at Pacific Crest Securities, told Reuters.

Adobe has been switching to web-based subscription for itsCreative Suite 6 from traditional box licences to attract a morepredictable recurring revenue.

Online subscriptions let customers access the latest versions of software for a monthly payment.
